Lizards found "extremely small" in Madagascar


سحلية من مدغشقر
Researchers fear that these lizards may face the risk the event of any disturbance in areas where they live
Researchers found in Madagascar on a smaller lizards in the world, and the length, eachabout 29 mm, and named it "Brukicea Micra."
Scientists also found Germans also had three other small species of lizards in the north ofMadagascar, according to a regular and Plus (PLoS ONE), which publishes basic researchin science and medicine.

Researchers fear that these lizards may face the risk the event of any disturbance in areas where they live.
The research team is headed by Dr. Frank Glao, from a Zologikh Stadtsamong of Animal Science in the German city of Munich (Zoologische "Staatssammlung).
The team has Glao experience in the study of small lizards in Madagascar, as it has alreadydealt with the study of other types of these animals in the past.
The team field trips in Madagascar in search of these small lizards that are easily ignored.
According to Dr. Glao that these lizards usually prefer to stay during the day amid the leavesfalling, while returning at night to climb trees, and thus are difficult to see.
A rare case
The scientists used searchlights to look for lizards in places where its presence is likely.Was found inside a small island in a remote Madagascar to small lizards believe it may represent a rare case of a dwarf living on the island.
He spoke of this phenomenon when diminishing the size of the organism with the passage of time to adapt to the limited habitat such as an island.
Dr Glao told the BBC: "Perhaps the large island of Madagascar has produced a core groupof dwarf chameleon objects, while objects may be the smaller of which may have arisen in the smaller islands."
The researchers conducted a genetic analysis to ensure that the lizards belong to different types.
Genetic differences
A member of the team of Vince Migaul Technical University of Braunschweig vs. Germany, the genetic differences between the factions seemed "clear".
He added: "This shows that these lizards separated from each other by millions of years."
Dr Glao: "Some species are concentrated in small areas of Madagascar, so it is importantto preserve."
Scientists believe that the small lizards sensitive to any disturbances occur on the areawhere you live.
